Hello,
I have read tons of materials but could not get a clear view what material do i have to choose to make Primaloft quilt.
I understand that Pertex Quantum is a good stuff but i have my needs:
1) This quilt will button in for my hunting clothing and therefore i cannot accept any nylon style noises. Jacket and pant will be made from (listing outside to inside) Polartec WindPro + Classic 300 + Primaloft One 5oz quilt when needed.
2) As it goes next to my base layer it should not block perspiration to escape and dry fast.

So if put together in short words – Quiet, breathable, dawn proof as required by Primaloft.

again, I am a bit confused as to how you will be using this. That being said, I recently finished a quilt out of Primaloft One and 4.5mm habotai silk and it is silent. If I were making any kind of garment this is the fabric that I would want in it.

David, I choose or considering Primaloft One over Climashield Apex because of higher CLO 0.92 vs 0.82 and Primaloft One being thinner that Climashiels Apex. Thickness is not important for sleeping bags, but i cannot move around during hunting like fat snowman :)
But from what i have read then Climashield is much easier to work with … that is a point worth considering also.

I have no experience working with (using) silk in terms of how it performs. How fast does it dry? How good it breathes when it's in down proof thickness/density? Doesn't silk when wet give you damp feeling? What i mean i doesn't it feel like wet cotton t-shirt sticking to your skin etc …. yuck ?

I used 8D for sleeping bag liner – very comfortable – quiet – cheap – almost as lightweight as 7D.

I think your logic about One being lighter for the same warmth is correct – but it'll just save less than an ounce so maybe it's not that important. If it requires more quilting, and where the quilting is it will be thinner so less warmth, so you will lose some of the warmth advantage.

Maybe you could ignore the quilting requirement. I have a small amount of One and the fibers go mostly in one direction, along the roll of insulation. So you could have the fibers running down from the top of the vest. There wouldn't be a lot of force pulling the fibers sideways in their weak direction.

But, maybe why screw with it – just use Apex even if your finished vest weighs 1/2 extra ounce.

Ok, lets say i will go with Apex. What lener material is best to choose? What about silk? Is it really breathable and does it dry fast? Maybe i should choose something else? Polartec PowerDry for example?

I listed some of the pros & cons of silk and 7d/8d IMO. Personally, I would go with 7d if you can afford it, if not 8d.

4.5mm-5mm silk
– is very breathable and light
– not as durable as 7d/8d
– dries fast
– cheap

7d/8d
– not as breathable as the above, but no slouch. 8d more breathable than 7d.
– 8d not quite as cheap as silk, 7d much more expensive
– feels much better on the skin(important for the liner in a quilt)

Ryan, what do you think about noise each of those materials make? Will 7d be quiet as fleece fabric or silk?
And will 4.5-5mm silk be down proof? Primaloft requires lining to be down proof. My guess is that during machine washing individual fibers might start to go through liner if it is not dense enough.

Which material feels better to skin? 7d better than silk?
Why would you choose 7d over 8d? I didnt get your point, sorry for beeing such annoying noob ;)
